RHS 80x40x3.2 Iberian tables · Weight & Dimensions

Iberian tables, cold-formed sections · Rectangular Hollow Section

Rectangular Hollow Sections (RHS) are tubular profiles with excellent torsional resistance and aesthetic appeal. Used for columns, trusses, and exposed structural elements.

Also known as: PTR 80x40 cal 11 (México) · Caño estructural 80x40 (Argentina)

The RHS 80x40x3.2 steel profile weighs 5.5 kg/m (3.70 lb/ft), has a depth of 80 mm (3.15 in), flange width 40 mm (1.57 in). Cross-sectional area: 700.67 mm². Moment of inertia Ix = 54.943 cm⁴, Iy = 18.411 cm⁴.
